(Filter Effects use them). It doesn't make sense to restrict them, just because we have a use case in mind where we could use a workaround. After all we mainly have fragments for resources, why would they still be allowed to use any fragment? Unless I did not misunderstand the proposal (may did not get all emails), I don't think this is a good idea at this point.

SVG fragments work with CSS Images on three different browsers (IE, FF, Opera) and will work in the near future in WebKit. So either CSS Images or Mediafragments should deal with it.
I personally don't see a disadvantage to reference images as paint server with a new 'image()' function: image(url(externel.svg#id)). Specific functions could be used directly like gradients or (later) element().
If we do it in SVG 2 at all. One thing that bothers me, is that we don't have the same technologies like the background properties, to stretch, clip and repeat images. So I think it won't do what you want most of the time. If we specify it, it might be delayed to SVG 2+ anyway since browsers will need some time to implement it.
